Arming and Refueling Points are places where combat aircraft can get gassed up and reloaded with weaponry, without shutting down. This allows them to get back into the fight fast with a low chance of breaking during restart. Like a pit crew but with high explosives. Here we see that rapidly loading the Apache's M230 30mm chain gun is a finicky task done best by hand.

H/T to Chris for sending this my way.
